The short answer is no. Legally, the equipment would need to have part 95 certification to be used on the GMRS bands. Take regular business band LMR radios for example, Some are both part 90 and part 95 approved, while others are only part 90 approved. even though all of these radios technically can be programmed for GMRS use, "Technically" the ones that are not part 95 approved are not legal to use. Your best bet is to ask what type of radios you want to use, then we can figure out if they are type accepted for GMRS use.
